[ Upstream commita8639a79e8] When an old ack_queue entry is used to store an incoming request, it may need to clean up the old entry if it is still referencing the MR. Originally only RDMA READ request needed to reference MR on the responder side and therefore the opcode was tested when cleaning up the old entry. The introduction of tid rdma specific operations in the ack_queue makes the specific opcode tests wrong. Multiple opcodes (RDMA READ, TID RDMA READ, and TID RDMA WRITE) may need MR ref cleanup. Remove the opcode specific tests associated with the ack_queue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
